SPRING-DAMPENER.

Application filed September 17, 1916. Serial No. 51,140.

Tooll whom it may concern:

Be it known that I, ARMZND I-I. PEYoK'E, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Spring-Dampeners, of which the following is a specification.

My invention relates to springs, and has particular reference toa novel spring dampener or spring control.

It has been found that the action of they springs which serve to resiliently support the bodies-of railway cars is peculiar. For

equalities are cumulative, the up and down movement under the action of the springs increasing progressively until the point is reached at which the springs are completely compressed and the vibration of the car body stopped thereby. This action is repeated many times in the travel of the car and is deleterious not .onlyto thesprings but to the roadbed and the car. This has been sought to be overcome by the use of greater capacity, springs, with the result that the required resiliency under light shocks is not present. The desired result may, however, be secured by the use of a dampener or friction element in connection with each nest of p ng The construction shown herein is intended as an improvement on the construction claimed ;in my co-pending application, Se rial No.42,693, filed July 30, 1915, Patent No. 1, 169,863 of February 1, 1916.

The invention will be more readily understood by reference to the accompanying drawings, wherein- Figure 1 is a vertical section through a dampener constructed in accordance with my invention, and Fig. 2 is a transverse section through the construction shown .in Fig. 1.

shown in this instance as of rectangular cross section, the flanged upper end 13 of which is suitably secured to. the top plate 10. Secured to the lower plate 11 are two friction elements 14, 15, each of which is triangular in cross section, both of which when united forming a square of the outline of the sleeve 12, and adapted to occupy the space interiorly of the sleeve. The inside portions of the members 14, 15 are recessed to accommodate springs 16, 17, 18, 19, the springs 16, 18 exerting their force at an angle of 90 to the springs 17 19. Thus the members 14, 15 are forced outwardly against the inner walls of the sleeve 12, thereby in dining a high frictional resistance to the up and down movement of the plates 10, 11 under the action of the springs confined therebetween. Theresult of such construction is that all teetering or cumulative compression of the springs is avoided.

Obviously other forms of the construction may be evolved, and such forms as are within the scope of my claims I consider within the spirit of my invention.

I claim:

1. In a spring dampener, the combination of upper and lower plates, a rectangular barrel secured to said upper plate, a pair of rectangular friction members secured to said lower plate and interfitting with said barrel, and two springs located interiorly of said friction members and tending to exert their force to spread said rectangular members, one spring exerting its force at right angles to the other thereof, substantially 'as described.

" 2. In a spring dampener, the combination of upper and lower plates, a rectangular barrel secured to said upper plate, a pair of segmental members secured to said lower plate, and two pairs of springs located interiorly of said segmental members, one pair of said springs exerting its force at right angles to the other pair of said springs, substantially as described.

Signed at Chicago, Illinois, this 14th day of Sept, 1915'.
